(Thomas Braun CEO of T-Ray Science has been kind enough to share the follow The IPO for T-Ray Science is looming. More on this later)
In response to your comments on CW THz systems I have attached some application notes from Toptica (the leading research laser company) on CW THz systems. The picture of the ceramic knife is using CW. We have the exclusive rights from MIT for the only known THz CW detection method which was patented in the USA. The inventors are well known in the THz community - Drs. Verghese and McIntosh of MIT Lincoln Labs. The system Toptica is advertising is using the CW detection method patented by Verghese and McIntosh. The Toptica application notes are excellent and give a good explanation of the technology which has now been exclusively licensed to our company. Toptica is interested in promoting the technology because the most expensive part of the system is the laser and theirs is considered the best.
Academics and universities may use the CW detection method freely, but commercial users have to take out a license from T-Ray Science. Those who do not have a license are stealing from us and MIT because we split the royalties with them under our license agreement.
CW systems are well into the THz range, and the advantage is the speed. Especially if you are doing quality control and you know what you are looking at. The pulsed systems take a while to acquire an image or signature as they sweep the whole spectrum. For any repetitive task, such as on a production line, this is not necessary.
T-Ray Science has the only dual mode (pulsed and CW) THz system in the world and we have filed a patent on it. The system was developed at the University of Waterloo by our CTO, Dr. Saeedkia, and the IP has been assigned to T-Ray. The dual mode system allows users to sweep the spectrum and when they find the absorption peak they can seamlessly switch to CW which has higher resolution and "zoom" in on the sample.
We also offer the only dual mode photo conductive THz chip in the world. We have them in stock and we are now selling them. Several leading THz research labs and companies are already using them. Our chip catalogue is down loadable from our web site.
So while pulsed mode system technology is in the public domain, CW and dual mode THz system technologies are owned exclusively by T-Ray Science which puts us at the forefront of the THz movement.

MY NOTE: (IT'S CERTAINLY REFRESHING TO HAVE THE CEO OF A COMPANY, RECOGNIZE THAT GETTING INFORMATION OUT VIA, A BLOG SUCH AS THIS ONE, IS FREE OF CHARGE, AND PROVIDES NEW EXPOSURE TO T-RAY SCIENCE, AS WELL AS TO THE FIELD OF TERAHERTZ TECHNOLOGY! I WISH T-RAY SCIENCE ALL THE BEST AND LOOK FORWARD TO RECEIVING ADDITIONAL INFORMATION FROM MR. BRAUN)
DISCLAIMER! I WILL REMOVE ANY COPYRIGHTED OR OBJECTIONABLE MATERIAL UPON REQUEST!
I think the intelligent reader will quickly discern that this system is a CW (continuous terahertz) system. Read the prior post, to get a more comprehensive view on CW. However, perhaps this really is a new development in CW, which makes the prior post incomplete or simply incorrect. It apparently has a unique dual wave/pulse feature, that I would like to know much more about. I welcome your thoughts and comment!
